Suddenly, I'm getting warm-but evil tinglies...
Imagine an IK/MN crossover, with Lord Toruk bursting forth from Cryx with his horde of trollkin, dragon-tainted humanoids and monsters... the pollution of his presence corrupting Immoren as surely as the Black Mirrors drain Eredane's mana... renegade heroes, hunted by mechanical astiraxes creatures that sniff out both magic and gunpowder...
Don't you love the imagery of weary, harried freedom fighters clutching worn handgunnes, valiently defending the last strongholds of the free peoples from the dragon tyrannt's warjacks? I know I do.
(Hurries to gaming bookshelf, grabs MN Campaign Book and IK Character Primer, starts tearing pages out of both and stricking back together at random...)
